Title: Method of cutting and sealing film
Inventor: MCDONALD GREGORY E
IPC: B32B27/08
Filed: 1998-07-21
Abstract: In the packaging of a wide variety of products in flexible film bags, problems with edge tear and incompleted bag cut-off have been encountered. The edge tear and incomplete cut-off are worse for films containing low melting polymers, such as metallocene-catalyzed ethylene/alpha-olefin copolymers. These problems can be solved using a clamp-cut-seal process, as opposed to a clamp-seal-cut process.  By cutting before sealing, the film is still cool, and the strain on the film due to the cutting does not pull on the seal area enough to cause edge tearing (i.e., tearing at the seal). The higher resistance to elongation of the cool, clamped film also serves to reduce or prevent incomplete bag tail cutoff. Also, by providing a means for sealing which clamps the film before it is cut, defective seals from bag "pull back" can be avoided.

Abstract: The invention relates to a method and device for regulating the concentration of metal ions in electrolytic fluid for depositing metal using insoluble anodes. Said electrolytic metal also contains compounds of an electrochemically reversible redox system. Metal is dissolved with its oxidized form in an ion generator (1) which is cross-flown by said fluid in such a way that the compounds are reduced. The dissolved metal ions reduced on the items to be treated in order to deposit metal. The compounds of the redox system are re-oxidized in their reduced form on the insoluble anodes in the electroplating plant (13). In order to keep the concentration of metal ions constant in the electrolytic fluid, at least one part of the electrolytic fluid contained in the electroplating plant is conducted through one or several auxiliary electrolysis cells (6) with at least one insoluble anode (8) and at least one cathode (7) and a sufficiently high electric current flow is regulated between the anodes and cathodes pertaining to the auxiliary cells so that the current density on the surface of the anodes is at least 6 A/dm2 and the current density on the surface of the cathodes is at most 3 A/dm2. The ratio between the surface of the anodes and the surface of the cathodes pertaining to the auxiliary cells is thus regulated to at least 1:4.

Abstract: A system and method for using a relief object image generator for cursor control, computer access control, and operational parameter control is disclosed. The system includes a relief object image generator (10), a sensor array (72), an image processor, and a memory. The relief object image generator (10) generates images of relief objects, such as fingerprints, brought in proximity of the exposed surface of the image generator (10). The image processor receives the image from the sensor array (72), processes the image, and compares the resulting descriptive information to stored information corresponding to authorized users. If a match is found, the user is granted access to the computer. The image processor may also process the image to determine image movement or the image's presence or absence. Detected movement is used to generate directional signals while the presence and absence of the image is used to generate highlight and select signals. These signals conform to those generated by known mouse devices so the system of the present invention can replace a position variable device in the keyboard of a laptop or other portable computer without sacrificing functionality for the system. Other uses of the system disclosed herein include control of operational parameters for a device such as brightness and contrast for a monitor and the transmission of relief object images to remote sites for authentication of a user.
